TYPE-WRITNG-VIACHIN ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 547,002, dated October1, 1895. Application filed October l5, 1891. Serial No. 408,841. (Nomodel.)

.To all whom it may concern:

Be it known that we, .TERRE B. ELLIOTT and ROBERT J. MAWHINNEY, citizensof the United States, residing at I/Vashington, in the District ofColumbia, have invented certain new and useful Improvements inType-Writer Attachments; and we do hereby declare the following to'be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to an improved attachment for type-writingmachines, and has for its object to provide an adjustable paperguideadapted to be attached to a Remington and similar type-writers, and whenso attached to facilitate the introduction of the paper and to guide thesame about the platen during the operation of printing, the guide beingmade adjust-able to properly guide and feed either a single sheet orseveral sheets of paper when manifolding. In connection with the saidguide is used a relatively-fixed guard, which may be provided with asuitable scale to indicate the point at which to commence the initialline of each page or sheet.

Our improvements consist in the novel features of construction andarrangement of parts hereinafter fully described and afterwarddefinitely pointed out in the claims, due reference being had to theaccompanying drawings, forming part of this specification, wherein-Figure l is a plan View of the blank from which the guide-carrying frameis struck up. Fig. 2 is a vertical longitudinal central section of theattachment, showing the same attached to the carriage of a type-writer.Fig. 3 is perspective view of the attachment, and Fig. It is a similarview of a modification.

Referring to the drawings, the letter A indicates the carriage of atypewriter; B, the friction wheel on which it travels; C, the platen,and D our improved attachment. The attachment consists of a flatmetallic bar E, bifurcated at one end, as at F, and bent downwardly at aright angle tothe body of thebar E for the purpose hereinafterdescribed. The opposite end of said bar is bent upwardly and in the areof a circle to forni a guard G, that lies substantially concentric withthe platen O, and two guard-arms II H are bent downwardly andpractically form a continuation of the guard G. To the under side of thebar E is riveted the guide I, consisting of a iiat strip of spring metalwhich at its free end is bent downwardly, as shown at t, and liesbetween the guard-arms H H. A setscrew .I is tapped through the barE andbears against the guide I, and by means of which the said guide is adjusted to or from the platen O. The bar E in rear of the guard-arms H His provided with a downwardly-projecting lug K, which is adapted to abutagainst the guide I and serve as a stop to limit the extreme movement ofsaid guide toward the platen C. The attachment is in the presentinstance secured to the carriage of the typewriter as follows: The screwL, upon which the friction-wheel B in machines of the nature describedusually has its bearing, is provided with a screw threaded extension Z,which engages a nut M, provided upon its inner face with a rectangularboss m. The bifurcated portion F ofthe attachment is caused to straddlethe boss m on the nut M, holding the nut against rotation and the screwL tightened up, clamping the attachment firmly between the nut andtheinner face of the carriage. Upon the front or convex face of the guardGand the guard-arms H H is marked a scale N, for the purpose hereinafterdescribed.

In making the attachment we prefer to strike up the bar E, itsbifurcated end E, the guard G, guard-arms H H, and stop K from a singlemetallic blank. A blank of the form shown in Fig. l is slotted at oneend to form 'the bifurcated portion F. The other end is provided Withtwo parallel longitudinal slits l 1 to form the guard G and guard-armsI-I H, and a substantially-U-shaped slit is cut or punched in saidblank, as at 2, and the metal bent downward to form the stop K, and theblank finally perforated andscrew-threaded, as at j, for the receptionof the screw J. Then constructed and secured in position, as abovedescribed, the xed guard G and the guardarms H I-I lie substantiallyconcentric and in proximity to the platen O, the end of the adjustableguide I resting under the guard G and between the guard-arms H H. As thepaper is fed into the machine the top or leading edge of the sheet isengaged by the down- IOO wardly-turned end of the guide and directedbetween the platen and the guard G. The guide is adjusted by means ofthe set-screw to bear with a sufficient degree of pressure against thepaper to properly hold it against the platen, the guide being depressedto accommodate several sheets, as in manifolding or where the article tobe printed upon is of unusual thickness. As the paper is fed into themachine the scale N will indicate when the proper point has been reachedat which to print the first line, thus insuring regularity in the copy.In introducing the paper it is not necessary to raise the carriage toenable the operator to direct the sheet under the paper-guide by hand,as is necessary in the Remington and similar machines now in use, theguide engaging the edge of the sheet and, in connection with the guard,directing and feeding the paper around the platen without any furthermanipulation.

In Fig. 4 we have shown a modification wherein the guard G andguard-arms H II are formed in one piece from a centrallyslotted curvedpiece of sheet metal and soldered, brazed, or otherwise suitably securedto the end of the bar E, the latter being bent down to forni stop K. Theoperation is precisely similar to that before described.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

l. In a typewriting machine, the combination with the paper carriage andits cylindrical platen, of a relatively fixed guard, and an independentdepressible guide arranged thereunderand in substantial continuationthereof for directing the paper between said guard and said platen, thesaid guide being adapted when depressed to move away from the platen tofacilitate thc introduction and guidance of several thicknesses of paperand ot' cards, tbc., substantially as set forth.

2. An attachment for typewriters comprising a frame adapted to besecured to the carriage of a typewriter, said frame having a relativelyfixed paper guard, and also an independent springpressed depressiblepaper guide arranged thereunder and in substantial continuation thereofand operating in the manner shown and described.

3. In an attachment for a type-writer a frame adapted to be attached tothe carriage and carrying a paper guard in combination with a paperguide for automatically directing and feeding the paper between theplaten and said guard and guide and means for adjusting said guidetoward and away from said platen, substantially as described and for thepurpose specified.

4. In combination with the frame adapted to be attached to the carriageof a type-writer and carrying a curved paper guard, the spring paperguide attached at one end to said frame and having its other end bentdownwardly as shown, and an adjusting screw carried by said frame andengaging said spring paper guide, substantially as described and for thepurpose specified.

5. The combination with the frame adapted to be secured to carriage of atype-writer and carrying a curved paper guard, the spring paper guideattached at one end to said frame and having its other end bentdownwardly as shown, an adjusting screw carried by said frame andengaging said spring paper guide, and a lug depending from said frameand serving as a stop for the spring paper guide, substantially asdescribed.

6. The combination of the frame adapted to be attached to the carriageof a type-writer and carrying an upwardly curved paper guard Y and twodownwardly curved guard arms, a spring paper guide attached at one endto said frame and at its other end bent downwardly between said guardarms, anda set screw for adjusting said spring paper guide,substantially as described and for the purpose specified.

7. The combination of the frame having the downwardly bentbifurcated endand provided at its other end with an upwardly curved guard and twodownwardly curved guard arms and provided with a downwardly projectinglug, the spring paper guide attachedat one end to said frame at itsother end bent downwardly between said guard arms, an adjusting screwcarried by said frame and engaging said spring guide, and ascrew-threaded bolt and a nut having a rectangular boss carried by thecarriage and adapted to engage the bifurcated end of the frame,substantially in the manner shown and described and for the purposespecified.

8. In a type-writer attachment the frame having a bent bifurcated endportion, an upwardly curved paper guard, two downwardly curved guardarms, and a depending lug, all struck up from a single blank, incombination with an adjustable paper guide and means for securing theattachment to a type-writer carriage, substantially as shown anddescribed.

9. In atype writing machine, the combination with the paper-carriage andits cylindrical platen, of a relatively fixed paper-guard (G) risingfrom said carriage, and an independent adjustable paper-guide (I)thereunder having an integral spring body or shank.
